About Cookie

Cookie Finance is a rapidly growing, VC-backed financial platform built for content creators. We started as a tech-enabled accounting service and quickly became the financial backbone for thousands of creators, influencers, and creator-led businesses.

Now we’re building our next chapter: a multi-product ecosystem of SaaS tools powered by unified financial data. Our platform sits at the intersection of creator income, business operations, and real-world financial behavior, giving us a uniquely rich dataset to build forecasting, personalization, and AI-driven financial insights that creators can actually use. We’re turning messy real-world creator finance data into products that scale.

About the Role

Our software engineering team builds our “Cookie Jar” web application which is an all-in-one financial platform for our customers and a workflow engine for our employees. The application uses a mix of in-house technology and external integrations with financial platforms including commercial banking, general ledger, payroll, and financial analytics.

We are hiring a Senior Node/React Engineer to help architect, build, and scale the next generation of the Cookie ecosystem. This role is for someone who thrives in high-growth environments. You will ship production code that directly impacts thousands of creators, influence technical decisions, and help shape the long-term architecture of a data-rich fintech platform.

You will report to the CTO and collaborate closely with Product and Operations to deliver scalable, reliable software.

What You'll Do

Design, build, and scale full-stack features across our Node.js backend and React frontend using TypeScript
Architect scalable systems that support financial data workflows, ledger logic, integrations, and analytics at growing volume
Own features end-to-end, from technical design through implementation, testing, and production release
Write clean, maintainable, well-tested code, including unit and integration tests that protect critical workflows
Collaborate cross-functionally with Product and non-technical teams to translate complex financial requirements into intuitive software
Contribute to technical direction and standards by participating in code reviews, improving CI/CD processes, and strengthening engineering best practices

What We're Looking For

5+ years of full-stack development experience, preferably in high-growth SaaS or startup environments
Proficiency in modern JavaScript/TypeScript ecosystems, preferably Node and React
Proficiency with relational databases such as Postgres and ORMs like Prisma
Experience incorporating AI tools (Claude, Codex) into your development process
Experience building scalable APIs and integrating with third-party services
Understanding of CI/CD pipelines, testing best practices, and production deployment workflows
Systems-thinking mindset, strong problem-solving skills, and comfort operating with autonomy in a fast-moving environment
A good sense of humor
